Wiki info about MiG-3-15

A single-seat monoplane fighter with an all-metal construction, closed cockpit and retractable landing gear with a tail wheel.
The fighter was initially developed by N.N. Polikarpov, and later by A.I. Mikoyan and M.I. Gurevich at OKB-155.
The experimental I-200 fighter took its maiden flight on 5 April 1940. The plane went into series production in June 1940 at aircraft plant No. 1 in Moscow under the designation MiG-1.
The MiG-3 model joined the series in February 1941, with a modified wing, larger landing gear, an additional fuselage fuel tank, a new radiator, modified flaps and self-sealing for the centerwing fuel tanks.
The MiG-3 series fighters were powered by the twin-row V12 Mikulin AM-35A engine with a maximum output of 1,350 hp. This was a geared-down engine with a single-stage supercharger and an air pressure regulator.
The armament on the first few MiG-3 series consisted of two 7.62 mm ShKAS machine guns with 750 rounds each and one synchronized large-caliber 12.7 mm Berezina BS machine gun with 300 rounds. All three machine guns were placed above the engine.
The design also allowed for the suspension of two containers under the wing, each housing an unsynchronized large-caliber 12.7 mm Berezina BK machine gun.
The plane's bombing equipment consisted of four locking DZ-40 bomb racks mounted under the wing, each able to carry up to 100 kg. The overall weight of its bomb load was no greater than 220 kg. The MiG-3 could carry the AO-8/-10/-25 and FAB-50/-100, cluster bombs and bottles of KS incendiary fluid.
The plane possessed the PBP-1A collimator sight, which allowed it to use all types of anti-air and anti-ground weapons.
Before the Great Patriotic War, the MiG-3 was the most prolific modern fighter in the Soviet Air Forces. From June 1941, it was widely used on the front in Soviet Air Forces units, naval aviation units and Air Defense Forces units.
In total, 3172 of these planes were made. The MiG-3's production ended in December 1941. Its use continued in Soviet Air Forces divisions until 1943, and in air defense fleets until the end of the war.
